Warmup

Discuss with your group what you remember about your molecular gastronomy technique

Suspension (thickening)

Colloid - a mixture where the solute remains as evenly distributed particles instead of dissolving

Suspension (thickening)Hydrocolloid - a special type of colloid where the particles like water (hydrophilic)

Xanthan Gum is a hydrocolloid

When the particles interact with water they stretch out and take up much more space, thickening the liquid

Agar Agar Spaghetti

This technique is an extension on the suspension technique

In the agar agar spaghetti technique a hydrocolloid (agar agar) is used again but this time it cross-links and forms a gel

Maltodextrin snow

Maltodextrin can absorb large amounts of fats. When it absorbs the fat the liquid turns into “snow.”

In your mouth the maltodextrin dissolves leaving behind the original ingredient

Spherification/Reverse spherification

+ Ca2+

Spherification, start with a liquid mixed with alginate and drop into calcium bath

Reverse spherification, start with a liquid that contains a high calcium content and drop into alginate bath
